Windows phone 8 和 Unity 5 支持 Facebook SDK
Windows phone 8 and Unity 5 support for Facebook SDK
这是对 Facebook SDK 支持 WP8 和 Unity 5 的请求。
我是一名开发人员，想要制作跨多个平台的游戏，并且能够将游戏发布到 Windows Phone 8 商店是我议程的重要组成部分。
是否计划很快发布对该平台的支持？如果是这样，您打算什么时候发布它？
此外，是否即将发布专为 Unity 5 设计的 Unity SDK？我已经设法让当前版本正常工作，但由于它尚未得到完全支持，我不知道什么可以，什么不能。
如能提供有关这些问题的任何信息，我们将不胜感激！
更新：我运行进入了这个解释"AndContinue"方法如何在windows 10中消失的视频，所以我们可以使用一种方法； windows 8/8.1 api 上已经存在的异步方法。在 https://youtu.be/aFVAP3fNJVo?t=23m34s

我和你在同一个地方，但设法让它工作了。有时间我可能会把我的经历写成博客。
下面是直接调用WebAuthenticationBroker的部分主要代码：-
static bool isTryingToRegister { get; set; }
private static string _FbToken;
public static string response;
static bool isLoggedIn { get; set; }
static private string AppID { get { return "000000000000000000"; } }
static private Uri callback { get; set; }
static private string permissions { get { return "public_profile, user_friends, email, publish_actions, user_photos"; } }
public static System.Action<object> AuthSuccessCallback;
public static System.Action<object> AuthFailedCallback;
public static string fbToken
{
get
{
return _FbToken;
}
}
static Uri loginUrl
{
get
{
return new Uri(String.Format("https://www.facebook.com/v2.0/dialog/oauth/?client_id={0}&display=popup&response_type=token&redirect_uri={1}&scope={2}",
AppID,
callback,
permissions));
}
}
public static IEnumerator _Run_ConnectWithFacebook()
{
yield return new WaitForEndOfFrame();
#if UNITY_EDITOR
UnityDebugAuthentication();
#endif
#if NETFX_CORE
WindowsStoreAuthenticate();
#endif
}
#if NETFX_CORE
static void WindowsStoreAuthenticate()
{
#if UNITY_WP_8_1 && !UNITY_EDITOR
AuthSuccessCallback = _Run_ConnectWithFacebook_SuccessResponse;
AuthFailedCallback = _Run_ConnectWithFacebook_FailedResponse;
UnityEngine.WSA.Application.InvokeOnUIThread(
() =>
{
callback = WebAuthenticationBroker.GetCurrentApplicationCallbackUri();
WebAuthenticationBroker.AuthenticateAndContinue(loginUrl, callback, null, WebAuthenticationOptions.None);
}, true);
#endif
#if UNITY_METRO_8_1 && !UNITY_EDITOR
AuthSuccessCallback = _Run_ConnectWithFacebook_SuccessResponse;
AuthFailedCallback = _Run_ConnectWithFacebook_FailedResponse;
UnityEngine.WSA.Application.InvokeOnUIThread(
async () =>
{
callback = WebAuthenticationBroker.GetCurrentApplicationCallbackUri();
WebAuthenticationResult authResult = await WebAuthenticationBroker.AuthenticateAsync(WebAuthenticationOptions.None, loginUrl);
}, true);
#endif
}
#endif
请注意我如何将 WebAuthenticationBroker.AuthenticateAndContinue 用于 windows phone 和 WebAuthenticationBroker.AuthenticateAsync 用于 windows 8. 这对于它们各自的平台是必需的。您可能想要研究获取 WebAuthenticationBroker，它是一个适用于 WP8 和 WSA 的 Microsoft class（我猜您的目标是 WSA，我也是）：-

您还需要 ContinuationManager.cs class 和 SuspensionManager.cs class 但主要用于 WP8.1 Universal。这对于 W8.1 是不需要的，因此您应该确保您使用#defines 将它们保持在它们自己的上下文中
如果您愿意，可以直接调用 facebook 应用程序而不是调用 WebAuthenticationBroker，但我不知道所有细节。您可以在 facebook 的网站 developers.facebook.com/docs/facebook-login/login-for-windows-phone 上阅读相关内容。如果用户没有安装该方法，则不推荐使用该方法。
长话短说，调用 WebAuthenticationBroker，处理 OnActivated 事件中的延续事件以捕获通过的 WebAuthenticationBrokerContinuationEventArgs 对象并使用您认为合适的数据。如果您想在统一端调用任何代码，请务必使用以下内容。请注意，您可以直接从 App.xaml.cs:-
访问 c# 代码
AppCallbacks.Instance.InvokeOnAppThread(() =>
{
// back to Unity
//your code here
}, false);
还要注意，这里主要是为了获取access token。一旦我们有了它，我们就可以直接向 facebook 进行基本的 WWW 调用并从中获取数据。数据将以 JSON 格式返回（ps 这是一种非常干净的格式！）您可以使用 .NET json 库将其序列化为 class .我使用 json2csharp.com 将任何示例输出转换为 class，我只是将其解析到 json 库中。
